  • inter and intraspecific competition of fat hen Chenopodium Album l and groundsel senecio vulgaris l
    Weed Research, 1994
    Co-Authors: J R Qasem, T. A. Hill
    Abstract:

    Summary: Resume: Zusammenfassung The responses of Chenopodium Album L. and Senecio vulgaris L. to inter- and intra-specific competition were investigated in both additive and replacement series experiments under glasshouse conditions. When grown with tomato the two weed species had similar effects on shoot dry weight at low densities but 5. vulgaris showed more competitive effect at higher densities. Weed density did not affect the concentrations of N, P, K, Ca or Mg in tomato shoots but dry matter and total amounts of nutrients were reduced increasingly with the increase in density of both weeds. The concentration of nutrients in the shoots of the weeds was not affected by density but dry matter yield and total nutrient accumulation per plant fell as the density increased. The concentrations of N, P, K and Mg in the shoots were higher in C. Album than S. vulgaris but that of Ca was lower. In a replacement series experiment the two weed species behaved differently. With C. Album, both dry matter yield and total nutrient per plant were reduced as its proportion in the mixture increased but, with S. vulgaris, dry matter per plant increased with its proportion in the mixture. One plant of C. Album grown with five S. vulgaris gave a higher shoot dry weight than when present in higher proportions or in a pure stand. In a pure stand of six plants the shoot dry weight per plant of C. Album was 26% of that of one plant grown with five S. vulgaris. In comparison, the shoot dry weight of one S. vulgaris in pure stand was 120% of that of one plant grown with five C. Album. The reduction in growth of C. Album was associated with a greater reduction in its ability to accumulate K than other elements. The competition index (CI) of C. Album in terms of dry weight decreased with its proportion in the mixture but the reverse was true for S. vulgaris. The relative competitive ability index (RCAI) of C. Album was almost 3–5 times that of S. vulgaris. The results showed that differences between the weeds in inter- and intraspecific competition were closely related to the growth of their root systems. Competition inter- et intraspecifique du chenopode (Chenopodium Album L.) et du senecon (Senecio vulgaris L.) Les reponses du chenopode (Chenopodium Album L.) et du senecon (Senecio vulgaris L.) a la competition inter- et intra-specifique ont eteetudiees en serre lors d'experiences a series additives ainsi qu'a series de remplacement. Quand elles etaient cultivees avec des tomates, les deux mauvaises herbes avaient des effets similaires sur la matiere seche des parties aeriennes a faibles densites, mais S. vulgaris se montrait plus competitif a fortes densites. La densite des mauvaises herbes n'affectait pas les concentrations en N, P, K, Ca et Mg dans les parties aeriennes de la to-mate. Par contre, la matiere seche et les quantites totales de nutriments etaient d'autant plus reduites que la densite des deux mauvaises herbes etait elevee. La concentration en nutriments dans les parties aeriennes des mauvaises herbes n'etait pas affectee par leur densite mais le rendement en matiere seche et l'accumulation totale de nutriments par plante decroissaient lorsque la densite augmentait. Les concentrations en N, P, K et Mg dans les parties aeriennes etaient plus elevees chez C. Album que chez S. vulgaris mais celle de Ca etait plus basse. Dans une experience a series de remplacement, les deux especes de mauvaises herbes se comportaient differemment. Chez C. Album, le rendement en matiere seche ainsi que la quantite totale de nutriments par plante diminuaient lorsque sa proportion dans le melange augmentait mais, chez S. vulgaris, la matiere seche par plante augmentait avec sa proportion dans le melange. Un pied de C. Album cultive avec 5 pieds de S. vulgaris produisait davantage de matiere seche aerienne que lorsqu'il etait present en proportions plus importantes ou en culture pure. Dans une culture pure de 6 plantes, la matiere seche aerienne par pied de C. Album representait 26% de celle d'une plante cultivee avec 5 pieds de S. vulgaris. En comparaison, la matiere seche aerienne par pied de S. vulgaris en culture pure representait 120% de celle d'une plante cultivee avec 5 pieds de C. Album. La reduction de croissance de C. Albumetait associee a une reduction de sa capacitea accumuler K, qui etait plus marquee que pour les autres elements. L'Indice de Competition de C. Album en terme de matiere seche diminuait avec sa proportion dans le melange, mais l'inverse etait vrai pour S. vulgaris. L'Indice Relatif d'Aptitude a la Competion de C Albumetait presque 3,5 fois plus eleve que celui de S. vulgaris. Les resultats montraient que les differences entre les mauvaises herbes en ce qui concerne la competition inter- et intra-specifique etaient etroitement liees a la croissance de leur systeme racinaire. Inter- und intraspezifische Konkurrenz des Weisen Gansefuses (Chenopodium Album L.) und des Gemeinen Greiskrauls (Senecio vulgaris L.) Die inter- und intraspezifische Konkurrenz von Chenopodium Album und Senecio vulgaris wurde sowohl in additivem als auch substitutivem Versuchsansatz im Gewachshaus untersucht. In Mischbestanden mit Tomate hatten beide Unkrautarten bei geringer Pflanzendichte eine ahnliche Wirkung auf die Spros-Trockenmasse, doch Senecio vulgaris war bei hohen Dichten konkurrenzstarker. Die Unkrautdichte hatte keinen Einflus auf den N-, P-, K-, Ca- oder Mg-Gehalt der Tomatensprosse, aber die Trockenmasse und der gesamte Nahrstoffgehalt nahm mit zunehmender Dichte der beiden Unkrauter ab. Der Nahrstoffgehalt in den Sprossen der Unkrauter wurde durch die Pflanzendichte nicht beeinflust, aber die Trockenmasse und der gesamte Nahrstoffgehalt nahm mit zunehmender Dichte der beiden Unkrauter ab. Der N-, P-, K-und Mg-Gehalt war bei Chenopodium Album hoher als bei Senecio vulgaris, doch der Ca-Gehalt war niedriger. In einem substitutiven Versuchsansatz verhielten sich die beiden Unkrautarten verschieden. Bei Chenopodium Album wurden sowohl die Trockenmasse als auch der gesamte Nahrstoffgehalt pro Pflanze im selben Mase reduziert, wie sein Verhaltnis im Mischbestand zunahm; bei Senecio vulgaris stieg die Trockenmasse pro Pflanze mit seinem Anteil im Mischbestand an. Chenopodium Album entwickelte bei einem Mischungsverhaltnis von l Pflanze zu 5 Senecio-vulgaris-Pflanzen eine hohere Spros-Trockenmasse als bei hoheren Verhaltnissen oder im Reinbestand. In einem Reinbestand von 6 Pflanzen war bei Chenopodium Album die Spros-Trockenmasse pro Pflanze 26 % der Masse einer Pflanze, die mit 5 Senecio-vulgaris-Pflanzen wuchs. Bei Senecio vulgaris dagegen war die Spros-Trockenmasse pro Pflanze im Reinbestand 120 % der Masse einer Pflanze, die mit 5 Chenopodium-Album-Pflanzen wuchs. Mit der Wuchshemmung ging bei Chenopodium Album eine Abnahme seiner Fahigkeit, K und andere Nahrstoffe aufzunehmen, einher. Der Konkurrenzindex von Chenopodium Album, bezogen auf die Trocken-masse, nahm mit seinem Anteil in den Mischbestanden ab, wahrend bei Senecio vulgaris das Gegenteil der Fall war. Die relative Konkurrenzfahigkeit von Chenopodium Album war fast 3.5mal so gros wie die von Senecio vulgaris. Die Unterschiede der inter- und intraspezifischen Konkurrenz der beiden Unkrautarten stand in enger Beziehung zur Entwicklung ihres Wurzelsystems.

  • Effects of leaf Chenopodium Album extractions on seedling related traits of Sorghum bicolor cultivars
    2014
    Co-Authors: M. Rezaei, A. R. Eivazi
    Abstract:

    Received: 31 January, 2014 Accepted: 28 March, 2014 Published: 20 April, 2014 In order to evaluate allelopathic characteristics of leaf Chenopodium Album extractions on germination and seedling growth of sorghum cultivars an experiment was carried out. A factorial experiment conducted based on completely randomized design with three replications under greenhouse conditions in Mianeh Azad University during 2009 season. Leaf extractions of 0, 25, 50, 75 and 100% of Chenopodium Album and five sorghum cultivars of Khaleseh, Galboos, Yengabad, Kimia and Spidfid arranged as different levels of first and second factors, respectively. Results showed that interactions of leaf extractions and sorghum cultivars were significance difference for traits of germination percentage, plumule and radicle lengths and fresh weights of them. With increasing leaf extractions reduced seed germination (44%) and the most germination percentage (100%) obtained at 0% extraction. The lowest seed germination (26%) was observed at Yingabad cultivar in 100% leaf extraction. This cultivar at 0% extraction had the highest plumule (227mm) and radicle (350mm) lengths. In contrast, the lowest lengths of plumule (86mm) and radicle (88mm) were allocated for Kimia cultivar at 100% leaf extraction. Within cultivars Khaleseh was tolerant for allelopathic characteristics of leaf Chenopodium Album extraction at seedling growth stage; therefore it can be cultivated under these conditions. © 2014 PSCI Publisher All rights reserved.

  • Allelopathic Properties of Chenopodium Album on Seedling Related Traits of Sorghum Cultivars
    International Journal of Agronomy and Plant Production, 2013
    Co-Authors: A. Bagheri, M. Rezaei, A. R. Eivazi
    Abstract:

    In order to evaluate allelopathic properties different parts of Chenopodium Album extractions on germination and seedling related traits of sorghum cultivars a factorial experiment was carried out in Mianeh Azad university at 2010 season. Treatments were arranged in three way factorial experiment based on randomized complete blocks design with three replications. Extract concentrations of 0%, 50% and 100% as control and three different parts of root, stem and leaf with five sorghum bicolor cultivars including Khaleseh, Galboos, Yengabad, Kimia and Spidfid allocated levels of A, B and C factor, respectively. Results of analysis of variance showed that leaf extraction reduced over 16% seed germination than root and stem extraction. Besides extract concentrations, root, stem and leaf parts of Chenopodium Album decreased 17, 26 and 43% germination percentage of sorghum cultivars, respectively. Extract concentration had less effect on the germination rate of Kimia cultivar. Extract concentrations of root, stem and leaf decreased 67 and 50% radicle and plumule lengths of sorghum cultivars overall. With in cultivars Kimia was tolerant for allelopathic properties of Chenopodium Album than others at early growth stage. Also Chenopodium Album leaves had better allelopathic properties than roots and stems
